Global Warming Update

The chart below plots atmospheric concentration of carbon dioxide alongside a global monthly temperature mean. Presumably there should be a correlation, as the theory of global warming posits that the greater the concentration of CO2, the greater the greenhouse effect.
















Instead, as CO2 has risen steadily, average global temperatures since 1998 have been in decline. The reason for the 1998 spike is the super El Nino that warmed the Pacific. (Via ICECAP)

Bravo! That graph should be on the wall of every school classroom in the world.

Not only is there very little correlation between CO2 and temperatures, there is no correlation between where the planet is warming and where the CO2 is densest. But there is a very good correlation between areas of greatest warming and areas of greatest geomagnetic change at the core-mantle boundary.

I think the real problem is oilout. That word you can Google, if interested.
